摘要
利用矢量曲线、γ因子等方法识别苍山ＭＳ５．２地震前泰安石英倾斜仪的前兆异常。分析认为：ＳＱ—７０石英倾斜仪反映出一定的地形变异常信息。
The precursor anomaly of quartz tiltometer in Taian seismological station is discriminated before cangshan earthquake of M s5.2 using vector curve and γ factor methods. Analysis show that SQ-70 quartz tiltometer can reflect certain anomaly informations of ground deformation.
